Specification of Letters Patent.

Patented Dec. 8, 1914.

Application filed April 23, 1912. Serial No. 692,705.

To all w/wmz't may concern:

Be it known that I, LIONEL F. Bownns, a citizen of the United States, residing at C0- lumbia, in the county of Lancaster and State of Pennsylvania, have invented a new and useful Friction-Coupling, of which the following is a specification.

This invention relates to an improvement in friction couplings.

The primary object of the invention is to provide a friction coupling, which when abnormal resistance is offered to the driven element, will cause said driven element .to discontinue its rotation. 4

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings-Figure l is an elevation partly in section, and Fig. 2 is an elevation with parts in section and viewed at right angles to Fig. 1.

In the drawings, designates the drive shaft, which is driven by any suitable motor. Arranged on said shaft'is a-sleeve l1 which is provided' with a plurality of extensions 12 and 14. These extensions are formed with the overhanging portions 15 and 16 which support the friction blocks 17, the portions 18 of the extensions 12 and 14 supportingcorresppnding blocks 19. Each of the extensions 12 and 14 are formed with housings20 in which are positionedcoiled springs 21, said springs contacting with the friction blocks or disks19, these springs being coiled about the studs 22 of the disks 24, the disks 24 being adjusted within the housing by screws 25 which are held in their adjusted position by lock nuts 26. It will be noted that by this construction the pres-.

sure of the blocks 19, may be regulated by adjusting the screws 25. Arranged on said shaft is a sleeve-27' on which is mounted the pulley 28, the power being transmitted to the driven mechanism through said sleeves 11 and 27. Formed integral with or secured to the sleeve 27 is a disk 30 which is disposed between the bearing blocks 17' and 19. It will be noted that as the drive belt which passes shaft -10 is rotated, the disk 30 will be locked to rotate with-said shaft through the contact of the disks or blocks 17 and 19, the disk 19 being held in contact with the disk 30, forcing said disk 30 in contact with the disk 17 thus transmitting motion to the over the pulley 28.

The friction coupling is designed for the conveyor driving mechanism of \laundry drying rooms. In an apparatus of this character a stripper is employed for removing the garments from the conveyer which is driven. It ofttimes occurs that the garment will hang upon said stripper or upon some obstruction in the drying room, or be held by the operator who is placing the garment upon the hangers of the conveyer and it is the object of the present invent-ion to design a friction coupling which when the .movement of the conveyor is stopped or in any way retarded will operate to allow the driving pulley to rotate freely upon the driving shaft. It will be noted'that in a friction coupling of this character when the movement of the conveying mechanism which is driven by means of the pulley 28, is retarded that the disk 30 will be caused to slip between the blocks 17 and 19 connecting the disk and the driving element, the disk slipping between the blocks. Thus the driving pulley 28 will remain idle on the driving shaft and the movement of the conveyor will beistopped' until the garment can be detachedffrom the stripper or other obstruction.

' The many advantages in a friction coupling of this character will be clearly apparent as it will be noted that the same provides a means whereby the movement of the conveyer mechanism will be stopped as soon as the same meets with an obstruction, thus preventing tearing of the garment which has caused thetemporary stoppage of the conveyer. a friction coupling of this character may be easily and economically manufactured and that the various parts may be readily assembled.

What is claimed is: j Afriction coupling, including two sleeves, a circular disk carried by one sleeve, a frame carried by the ,other sleeve and composed of two oppositely extending arms,

each of which is provided with a disk-embracing terminal, and cotiperative'fixed and It will also be noted that adjustable resiliently supported frietiorl blocks carried. by

each disk embracing terminal and its carrymg' arm. for engaging the opposite faces of the disk at diametri- 5 cally opposite points, one block of each paif being resiliently supported.

In testimony that I claim the foregoing
